SEPARABLE BUTTON.

SPECIFICATION forming part of Letters Patent No. 546,162, datedSeptember 10, 1895.

Application filed August 11, 1894:. Serial No. 520,070. (No model.)

To aZZ whom it 72mg concern.-

Be it known that I, WILLIAM L. KING, a citizen ofthe United States,residing at lVinston, in the county of Forsyth,State of North Carolina,have invented certain new and useful Improvements in Separable Buttons,of which the following is a specification, reference being had thereinto the accompanying drawings. v

This invention relates to certain new and useful improvements inseparable buttons of that class in which the head of the button has ashank adapted to be engaged by a plate with a radial slot enlarged atone end and so arranged as to fasten the button to the fabric; and ithas for its objects, among others, to provide a simple and efficientbutton in which the fastening is but a single disk of metal and whichcannot become accidentally disengaged from the shank of the button afterbeing once securedto the fabric. The fastening-plate is formed with aradial slot having at each end an enlargement, said en largements beingof different sizes, and the shank of the button having two portions ofdiiferent diameters with an annular groove between them and the headhaving a shoulder for preventing the lock-plate from slipping about onthe shank.

Other objects and advantages of the invention will hereinafter appear,and the novel features thereof will be specifically defined by theappended claim.

The invention is clearly illustrated in the accompanying drawings,which, with the letters of reference marked thereon, form .a part ofthis specification, and in which- Figure 1 is a perspective view of thebutton and its fastening-plate separated and the shank about to enterthe larger opening in the fastening-plate. Fig. 2 is a similar viewshowing the plate with the slot opposite the groove in the shank andabout to be moved laterally in the direction of the arrow. Fig. 8 is alike view showing the plate thus moved and in position to be movedoutward on the shank. Fig. 4. is a similar view with the fas Fig. 5

toning-plate in its outermost position.

is a sectional view with parts in elevation with the button attached tothe fabric.

Like letters of reference indicate like parts throughout the severalviews.

Referring now to the details of the drawings by letter, A. designatesthe head of the button provided with a shank B. This head may be of anydesired shape and as ornamental or fanciful in appearance as may berequired. The shank may be a'liixed thereto in any suitable manner. InFig. 5 the shank is shown as provided with a head I), which is confinedbetween the two parts of the head of the button, as shown. This,however, is but one of the many ways in which the shank and head may beunited. The shank is provided at a point about midway of its length withan annular groove 1), beyond which the shank is reduced in diameter, asseen ate, and the end of this reduced portion is provided with a flangecl, as seen in the various views, which serves to prevent displacementand undue movement of the fasteningplate.

D is the fastening-plate. It is provided with a central circular opening9, which communicates by the narrow radial slot 6' with a larger opening,1 nearer the periphery of the plate, as seen best in Figs. 1 and 2. Thecircumference of the openingf is like that of the larger portion of theshank of the button or that part thereof between the head and thegroove, while the circumference of the smaller opening a is the same asthat of the smaller portion of the shank or that portion between thegroove and the flange d.

Vith the parts constructed substantially as above set forth, theoperation is as follows: The shank is passed through the material E inthe usual way, as by a threading-thimble or the like, and then the freeend of the said shank is passed through the larger hole f in thefastening or look plate D until the plate comes opposite the groove 6 inthe shank, when the plate may be moved laterally, its portion or slot 6'moving between the opposite walls of the groove, and the plate moveduntil the shank is in line with the central and smaller hole e of theplate, when the plate the plate could not become detached, as, in.

order to become disengaged from the shank, it has to move lengthwise ofthe shank till opposite the groove of the latter, and then it 'must movelaterally till the shank comes coincident with the larger hole of theplate, which movements cannot take place under any circumstances.

I deemit important that the annular groove in the shank beot a lengthequal to the thickness of the fastening-plate, as shown, so that thefastening-plate cannot become distorted or at an angle other than aright angle to the shank, and hence all danger of separation is avoided.Furthermore, this construction provides for some play of the goods uponthe shank between the'plate and the button-head and dispenses with theemployment of anti)- ber sleeve, which has heretofore been employed inconnection with this form of fastelling-plate, as-in the patent toGengembre, No. 45,400, dated December 13, 1864, the construction ofwhich I hereby disclaim.

That is claimed as new is- The improved separable button hereindescribed, consisting of a button head having permanently attachedthereto a shank having at its outer end a head, a reduced portionadjacent to said head with a portion of larger diameter adjacent to thebutton head and an annular groove between the reduced and larger portionof the shank and of a length substantially equal to the thickness of thefastening plate, and a fastening plate having. a central opening ofadiameter substantially,
